We're less than a week from Father's Day 2018, which is when we'll (hopefully) crown a US Open champion at Shinnecock Hills for the fifth time. It's also one of the best days of the year, when dads are showered with some praise for being adequate, loving parents. That praise usually comes with a nice card (preferably homemade) and a gift or two.

Dads who golf love golf gifts. They especially love golf gifts they can use again and again to be reminded just how lucky they are to have such great children -- or a wife who picks out the gifts for said great kids.

So, if you're still hunting for great Father's Day gifts for dad, we have some golf-related suggestions under $100.

2UNDR golf underwear: Walking the golf course can lead to a lot of uncomfortable chafing and rearranging of shorts and pants. But with 2UNDR underwear, made specifically for golfers, dad will feel dry, comfortable and energetic from the beginning to the end of the round. They also make underwear for every other purpose in life, and their loungewear is amazing. You can save 20 percent on your 2UNDR order (of any size) with promo code GNN20 at checkout.

Izzo Swami golf GPS watch ($70): Every golfer needs to quickly know how far they have to hit each shot. This reasonably priced Izzo Swami golf GPS watch will do just that. It isn't as feature-packed as other products in this space, but it'll do the job and make dad happy. Save $30 on the normal price.

Orange Whip trainer ($99 with promo code): Golfers need to warm up before their round, and they can always work on strengthening their core muscles and control of the club. The Orange Whip trainer does all of those things effortlessly. It's a counter-balanced swing tool with a grip on one end and a weighted orange ball on the other to promote muscle flexibility and swing control. It's a life-saver. Use promo code GNN at checkout to save 10%!

Grip Boost golf grip spray ($13): Golf grips need to be a little tacky to work their best for golfers. However, between sweat and rain and wearing down over times, grips can lose that tackiness. Grip Boost golf grip spray changes that with a few sprays from the bottle, which comes with a handy clip to put on dad's bag. Within seconds, dad will feel instant tack on his grips and/or golf glove that'll last the whole round through!

Seamus Golf headcovers ($50 and up): Seamus Golf makes great headcovers, travel bags, divot tools and other unique accessories for golf. All of it is phenomenal. However, if you want to get something quick and easy, go for a headcover. These bespoke covers are made by hand, and they come in a variety of unique patterns.

Secret Golf membership ($70): Maybe your dad needs to get better at golf. And by maybe, we mean, almost certainly. So why not learn from the best? Secret Golf's roster of major-winning golfers will show your dad how to play his best golf, continually improve and achieve his golf goals. He can thank you later. Get one month free!

If you need a last-minute suggestion, and these gifts don't seem like they'll fit the dad you're buying for, hit me on Twitter @RyanBallengee for your questions!
